BRX Do-More PLC to Modbus TCP RTU Remote IO Controller BX-MBIO

The BRX Do-More PLC can communicate to a remote I/O (input and output) controller modules using the Modbus protocol for communications. The BX-MBIO provides both Modbus RTU and Modbus TCP interfaces. Modbus RTU is a serial communication and Modbus TCP is an Ethernet communication. Modbus RTU is supported over an RS-485 serial connection. Modbus TCP is supported over an Ethernet connection. They function as listening/replying devices (slave, server) and can connect with any mastering (master, client) device that communicates using the Modbus protocol.
Previously we looked at the BX-MBIO Modbus RTU TCP Remote IO Controller wiring and configuration.

We will connect the BRX Do-More PLC to the Modbus remote IO. This will be done using the Modbus TCP and Modbus RTU protocol. Ethernet and serial RS485 communication to the BX-MBIO unit will be the media.
The BX-MBIO remote I/O expansion units feature the following:
• RJ45 Ethernet port for communications via Modbus TCP
• RS485 serial port for communications via Modbus RTU
• Supports up to 8 additional Expansion Modules (Add the discrete or analog I/O you require)
• AC and DC powered units available
• AC powered units include an integral 24VDC auxiliary output power supply
• Power connector and serial port connector included

BRX PLC Analog Dusk to Dawn Program

A dusk to dawn sensor usually is discrete on/off of the lighting control. If we want to vary the lights to mimic more of the sunset and rise, we would use an analog output to control the lights. I was recently asked about such a program. Every day they wanted the lights to go off at 10 pm and come back on at 6 am. At 9:30 pm the lights would be on at 70% or 7volts of a 0-10V signal. In the next half hour, the program will bring the lights from 70% down to 0%. In the morning the lights will come back on within the half-hour from 0% to 70%. Poultry Farms are one place that would utilize this program.

We will be developing a program that will do this with our BRX PLC (Do-More). Let’s get started! Continue Reading!

BRX PLC HTTP JSON Instructions

One of the features of the BRX Series PLC is the ability to expand its capability to fit your application. Software and hardware changes are ongoing so the PLC can grow with your needs. Communication is something that the BRX PLC can do very well. As part of the internet of things (IoT), the BRX will share and exchange data. You can also refer to this as the industrial internet of things. This will suit several industrial applications.

The Do-more Updates Release 2.5.2 on April 22, 2019, has introduced new instructions. Here are the instructions that we will be using:
HTTPCMD – HTTP Request / Response with Server (BRX only)
JSONPARSE – Parse JSON Text (BRX only)
We will be using these instructions to read the weather conditions from a website. Let’s get started. Continue Reading!

C-More Micro HMI Object Text

The C-More Micro HMI Panel software uses virtual components called Objects. Five different text objects are available for your industrial human machine interface. (HMI) Static text will place words on your HMI page. Lookup text will display a message corresponding to a value in a tag register. Dynamic text will display the ASCII (American Standard Code for Information Interchange) equivalent of the information in the tag register specified. Scroll text will display information too large to display in the area assigned. This will move the information in the display area so the entire message can be seen. Text entry will allow the user through a pop up key pad to enter ASCII characters into a tag register.

We will now look at all five of these text objects our HMI micro panel. A new page will be made to show all of the text object functions and operations. Let’s get started. Continue Reading!

C-More Micro HMI Object Recipe

The C-More Micro HMI Panel software uses virtual components called Objects. Recipe buttons are part of these objects. The Recipe Button Object changes the value of a tag or multiple tags. The Recipe Button Object looks and acts like a Pushbutton Object on the screen. When the Recipe Button Object is pressed, the values in the Source Data Tags are written to Destination Data Tags.

We will now look at recipes that we can use with our HMI micro panel. They include the recipe button. We will program 3 recipes into the unit that will control 4 different timers. Let’s get started. Continue Reading!

C-More Micro HMI Object Bitmap

The C-More Micro HMI Panel software uses virtual components called Objects. Bitmaps are part of these objects. These bitmaps are images that are made up of tiny dots called pixels. Each of these dots are actually a small square that contains one colour. Bitmaps will help you produce simple, intuitive looking human machine interfaces.

We will now look at bitmaps that we can use with our HMI micro panel. They include bitmap buttons, static bitmap, dynamic bitmaps and multi-state bitmaps. Let’s get started. Continue Reading!

C-More Micro HMI Object Meters and Graphs

The C-More Micro HMI Panel software uses virtual components called Objects. Meters and Graphs are part of these objects. They can represent a range of numbers and are programmable to simulate the functions that you require on your automation project. This helps you produce simple, intuitive looking human machine interfaces.

We will now look at the meters and graphs that we can use with our HMI micro panel. They can replace the older chart recorder equipment that is still in use in some manufacturing facilities. These objects will represent the data in the PLC for the user to interpret. Let’s get started. Continue Reading!

C-More Micro HMI Object Numeric Entry

The C-More Micro HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Several of these objects can be placed on one panel screen and you can have multiple panel screens. This helps you produce simple, intuitive looking human machine interfaces.

Continuing from last time we will now look at the numeric entries that we can use with our HMI micro panel. Let’s get started. Continue Reading!
